    Abstract: Data transfer apparatus (211, 213) for a radiotelephone peripheral using a time multiplexed data bus for communication with a bus master of the radiotelephone (201) couples peripheral devices external to the radiotelephone (201) and other user information inputting devices, such as a handset (203) for a cellular mobile radiotelephone, to the radiotelephone central processor and speech processor (207). The data transfer apparatus generates time slots in frame formats in which the information is sent over the data bus. The entire message, information bits and the header, sent in a time slot from a peripheral device to the bus master is used to determine bus contention. Bus contention resolution during the start-up of data bus operation sets the priority with respect to other data transfer apparatus with which a peripheral device data transfer apparatus is able to access the bus during normal operation.

    Abstract: A controller (105) for a radiotelephone (100) having the capability of operation in both a secure mode for call authorization and a nonsecure mode for user interface is disclosed. The nonsecure mode and secure mode of operation are both resident in a single microcontroller (201) which runs the nonsecure operations until a requirement for the secure operation is requested during call placement. The nonsecure mode is disabled during the period of time the secure mode is operational and is reenabled upon completion of the secure mode operation. The secure mode cannot be accessed externally to the microcontroller (201).

    Abstract: An analog frequency inversion scrambler employing an exchange of random number seeds between an originating scrambler (103) and an answering scrambler (107) to create two pseudo-random frequency hopping rolling codes has been disclosed. The rolling code used in one direction of a duplex channel is different than the rolling code in the opposite direction and each code is synchronized by periodic synchronization signals.
